This report proposes an algorithm for recognizing the vehicle model type from time-sequence road images. This method consists of vehicle segmentation, front part detection, vehicle type recognition based on model shape classification, and recognition of inter-frame integration. The experimental result using time-sequence road images shows the proposed method is effective: the vehicle detection and the recognition rates of the proposed method are much improved.

The aged society arrives and the increase of the driver is remarkable. We aren't too much considered even about the eyesight difference among the general drivers in addition to the old driver. Therefore, we are studying about the new driving support system which reinforces the eyesight of the driver.

This paper proposes a system of "Digital Book-rest". The system overlays annotations on paper documents using a camera-projector system. The prototype system determined the position of a paper from the estimated corners of the paper, and it accurately overlaid annotations, such as circles, squares, and lines, on the paper.

We are developing a painting pictures and writings input unit for the diagnosis of the dementia patient. The characteristic of this equipment is that the facial image can be taken without making an examinee be conscious of the camera using the prompter. Moreover, this equipment can be utilized as the general psychological experiment equipment.

We propose the new measurement method which detects an eye-movement through the half mirror. This equipment can take a corneal reflex image without being interrupted by the eyelid. Also, the examinee can not see the camera which takes an eyeball and it is suitable to psychological experiment.

The audio information to be processed by driver is increasing yearly because of car navigation system's diffusion. In this research, we studied the temporal properties of human's audio-visual information processing and appropriate timing of audio information. Then, it became clear that timing is before 140ms from presentation of visual information.

In this paper, we propose a fast MPEG-2 to H.264 intra transcoding method. In our proposed method, we exploit DCT coefficients of MPEG-2 to determine the blocksize and the prediction mode of intra prediction for H.264. Our proposed method reduces the complexity by about 60% while maintaining similar PSNR.

The new possibilities brought by digital broadcasting are expected to lead to sophisticated information services utilizing broadcasting and communication networks. This paper proposes methods for content distribution and charging that can protect the usage history of users from the content provider while charging the user properly according to total usage.

In digital broadcasting, the content copyright is protected from illegal use with CAS (Conditional Access System), and subscribers can not watch/listen contents outside their houses. But subscribers require usability of contents. We propose a new type of pre-paid contents viewing system, which improves usability of contents. This system is a combined system of conventional CAS and mobile system, such as mobile phone, and it enables subscribers to watch/listen contents outside their houses with pre-paid tickets.

We propose a content consumption management system, which verifies the location where a subscriber watches/listens to contents. This system searches the path from start point to arrival point and periodically verifies the correctness of the location where contents can be used. This system can improve usability of contents and enables content providers to manage content consumption.

We propose a framawork of "active information presentation" for translation aid, which minimizes human translators' effort. The system automatically extracts expressions that might be unfamiliar to a translator, and then searches their translations from various resources and offers the results as the "translation parts."

We are developing a TV-camera career using the Segway^<TM>. The control performance has been improved by employing a linear-actuator to move faster the weight forward and backward which is used for the center of gravity movement. The TV-camera career has enough performance to run up a 12-degree slope.
